Irssi is a terminal based IRC client for UNIX systems. It also supports SILC, XMPP and ICB protocols via plugins.

Even the dpkg bot in #debian agrees irssi rocks:
<dpkg> i guess irssi is the best <IRC> client ever. "aptitude install irssi" and read . See also

Howto fix long boot delay with "Starting MTA:" (Common Issue)

Posted 06-10-2010 at 01:20 PM by bittner (Notes on Linux)
Tags debian, exim4, mta

A common issue when setting up servers in a lab is that the Mail Transfer Agent (MTA) delays the boot process waiting for a very long timeout. In the forums on the web this reads as ...

Howto build your own Debian repository

If you write software for Linux and you write them for Debian systems (Debian, Ubuntu, and others) you may want to provide your software as .deb installation packages. And one day eventually you will want to set up a repository so others can download and install your software without fuzz.

If you look at a Debian mirror (e.g. you will find out one day that packages and meta information is split up into two main directories on the root level:
